Abstract: 353,063. Shuttleless looms. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Wonder Weave, Inc.; 301, Congress Street, Boston, U.S.A.) April 16, 1930, No. 12079. [Classes 142 (1), 142 (ii), and 142 (iii).] Eyed-arm weft-inserting mechanism.-The weft C is inserted in loop form by a feeder 27, 26, 28 on a shaft 25, which maintains the weft in permanent loop form and is oscillated by bevel gearing from a shaft 11 driven by lever mechanism 58, 57, 59 from a disc 51 on the main shaft 54. The weft extends through guides 19 and is tensioned by passage between two discs 20, which are pressed together by a spring adjusted by a nut. The weft then passes through a horizontally adjustable guide 23 to a guide 28a on an arm 28 adjustably mounted in a collar 29 adjustably secured to the shaft 25, thence to guides 27a, 27b, 27c on the feeder. The amount of slack in the weft may be varied by relative adjustment of the guides 23, 28. Selvages, protecting.-The pull on the weft as the feeder enters the shed may be taken by a "temple" pin 35 on the arm 34a of a spring- controlled lever 34a, 34b, which is oscillated by a cam, or by a " temple " pin on a lever which is engaged by the reed when it beats up so as to depress the " temple " pin. Alternatively, or in addition, the pull may be taken by one or more warp threads A<1> at the near edge of the fabric which pass from a separate supply through a separate guide 41a and tensioning device 41c. Selvages, forming.-The selvage is formed bv a binder thread from a braked bobbin in a stationary carrier 43, around which the feeder carries a loop of weft, the carrier being releasably supported in a manner described to allow the loop to pass around it. The binder thread is guided by a hook 52 embracing the fabric and extending from a holder 53. Beat-up motions; reeds.-The feeder and reed oscillate together, one being forward when the other is back. The reed is caused to dwell when retracted and comprises bent dents 32 projecting from a shaft 33 having an arm 32a connected by a link 64 to a pivot 62, which connects a part 63 pivoted at 63a to a link 61 connected to a pivot 60a on a crank 60 on a disc 51a on the shaft 54. Take-up motions.-The fabric, which is steadied by passage over and under guides 14a, 14b is taken up by a sand roller 3 pressed upon by a roller 4 and driven by ratchet gearing operated by lever mechanism from a crank 11 a on the shaft 11. Let-off motions; warps, tensioning &c.-The warp passes from a beam geared to a brake wheel thence over two guide rollers and under an intermediate roller carried by a spring-controlled lever linked to a brake lever acting on the brake wheel, so that as the warp tension increases, the brake is retracted. Shedding-motions; healds.-The harness shafts 15 guided at 16 are reciprocated by links 18 from a rocker 17 operated by a link 56 and gearing 55.

Title: Improvements in reduction of metal oxides
IPC: C22B5/06
Filed: 1952-05-13
Abstract: In a method of producing metals or alloys, by smelting high-grade oxide ores, in which the entire amount of metal is produced by melting ore, reducing agent and a flux to form molten metal and slag, the reducing agent consists of substantially pure carbon and a non-carbonaceous material in relative proportions such that the carbon is calculated to combine with 48-85 per cent of a given weight of oxygen to form carbon monoxide and the non-carbonaceous reducing agent is calculated to combine with 15-55 per cent of that given weight of oxygen to form its oxide. The total amount of reducing agent is at least that theoretically required to reduce all the oxide of the metal, the process producing a metal containing not more than 0.15 per cent of carbon and the non-carbonaceous reducing agent and not more than 0.1 per cent of these individually.  Preferably the relative proportions of the two reducing agents are such that they are approximately equivalent as regards their oxygen combining capacity.  The carbon used may be in the form of charcoal and a part of the carbon may be combined, e.g. as silicon carbide or calcium carbide.  The non-carbonaceous reducing agent may be selected from the group p  aluminium, silicon, ferro-silicon, aluminium-ferro-silicon or mixtures of these.  Among the oxides which may be reduced are those of iron, chromium, molybdenum, tungsten, vanadium, nickel and cobalt or mixtures of these with the production of the metals or alloys, particularly ferro-alloys.

Abstract: 528,451. Measuring fluid pressure. COSSOR, Ltd., A. C., HUMPHREYS, T. D., and DODDS, E. M. April 24, 1939. No. 12259. [Class 40 (i)] [Also in Group XXXVI] An element suitable for measuring fluid pressures comprises a diaphragm arranged for one of its faces to be exposed to the pressure to be measured, while temperature-maintaining liquid is passed in contact with substantially the whole of the other face. The condenser element shown in Fig. 1 comprises a diaphragm la integral with a steel body 1 which has a screw thread 1b for insertion into an engine cylinder &c. A member 2 is formed with a web 2a and is riveted to the centre of the diaphragm 1a. Adjacent and parallel to the plane top face of the member 2 is the plane bottom face of a member 6 which is carried by a synthetic resin insulator 7 supported by a threaded steel sleeve 9. This sleeve is screwed into a second sleeve 3 which is screwed into the body 1 and grips the edge of the web 2a against a seating. The members 2, 6 form the moving and fixed plates of a condenser, the member 2 being constrained by the diaphragms 1a, 2a to move so that its upper face is always perpendicular to the direction of movement. Electrical connection to the member 6 is made with screened aero ignition cable secured in the sleeve 9 and making contact with the point 6a of the member 6. The diaphragms 1a, 2a form the top and bottom walls of a chamber through which cooling water, or other liquid such as oil, is passed by way of ducts 5 and pipes 4. In a modification, Fig. 2, the diaphragm 1a forms the moving plate of the condenser, there being two fixed plates 11, 12 formed as D-shaped heads on rods 11a, 12a. The cooling liquid serves also as the dielectric of the condenser. Water from the mains may be employed if the condenser is connected in a circuit supplied by alternating current of a frequency higher than the highest frequency of pressure variations to be measured. The pressure measurement is obtained by measuring the resulting modulation of the alternating current in frequency, phase or amplitude. In the construction shown in Fig. 1 ducts may be provided to enable the cooling liquid to pass between the plates 2, 6. In the construction shown in Fig. 2, the moving plate 'may be formed by a member similar to the member 2, Fig. 1, without the integral diaphragm 2a.

Title: Improvements in or relating to apparatus for submarine signaling
IPC: G01S15/10
Filed: 1944-07-03
Abstract: 635,334. Echo sounding and distancemeasuring apparatus. STEVENS, A. H. (Submarine Signal Co.). July 3, 1944, No. 12674. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 1, 1946.] [Class 118 (ii)] In submarine echo ranging by means of ultrasonic compressional wave signals of duration less than twice the time of travel over the range to be determined, the projector emits frequency-modulated beam signals whereby the cumulative effect of random echoes is reduced. As shown, the frequency of the oscillations applied to the projector .21 by the oscillator 19 is varied within a comparatively narrow band by rotation of condenser 27 by a motor 26. Power is applied to the motor 26 and the oscillator 19, and the projector-receiver 21 is transferred to the latter from the receiveramplifier 22, by relays 25, 23 and 20 respectively, operation of which is initiated by a key 40, maintained by a holding relay 31, and terminated by the temporary breaking of contacts 30 by the arm 28 on the condenser spindle. In modifications, the frequency variation is obtained by varying the load across the secondary winding of a transformer coupling the input side of the oscillator 19 to a sweep circuit, the latter in one case comprising a vacuum tube whose conductivity is varied as a condenser, connected between grid and cathode by a relay energized by the operating key, is discharged through a resistance, and in another case comprising two resistors in series with a rectifier tube, the total impedance varying as a condenser connected across one resistance becomes charged; in this latter case the oscillatory voltage from the transformer secondary is applied to the sweep circuit by varying the conductivity of. a vacuum tube connected across the secondary, the cathode of which tube is earthed by the operating key. Instead of using the projector 21 as a receiver, a separate receiving system may be employed, and the earphones 32 or loudspeaker may be replaced by an indicating device.
